The Lowdown
Well, folks, it’s Rusty here, and I gotta be straight with you—this stretch is a tough one for southern Maine. Looking at the whole 16-day window, the truth is there’s barely a pulse. We’ve got a long, flat run ahead with only a fleeting moment of something slightly rideable, but nothing that’ll get the heart pumping. It’s the kind of spell where you’re better off checking the tides for a longboard paddle or just waitin’ for the next system to light a fire.
The only spot we’ve got on the radar is Kennebunk Beach. The water’s running at 65°, which is a touch warmer than normal for the time of year—nice on the skin but not much help for the waves.
Our first real hint of life comes on Saturday, September 5th in the afternoon. The breeze swings offshore from the NNE at 12 mph, cleanin’ things right up, and we see a small bump of 4 ft from the ENE, with a period of 7 seconds. The combined wave energy sits at a weak 188—barely enough to grunt. It’s surfable, but I’d call it ordinary at best. The break is sheltered from the swell direction, so it’s gonna be fat and weak, mostly for a longboard or a funboard if you’re desperate for a slide. It’s a beach break, and with such short period, it’s not gonna have much push. For a beginner, 4 ft is fine, but there’s no power behind it.
After that whisper of action, the surf flatlines completely. From Sunday, September 6th all the way through to the end of the forecast on September 19th, every single session is rated as poor surf conditions. We’re talking tiny dribbles of swell, cross-onshore winds, and energy readings that mostly stay in the single or low double digits. There’s a morning on September 15th with a glassy surface and 4 ft from the SSE, but it’s a short-period 6-second windswell with no direction on it—feels more like a lake ripple than a wave. Not worth paddlin’ out for.
Truth is, this is a blank run. Kennebunk Beach is inconsistent at the best of times, and with this pattern, there’s just no swell reaching that sheltered south-facing shore. If you’re into kitesurfing, a few of those afternoons with moderate cross-shore winds might be worth a look, but for a surfboard? Not this time.
Stay patient, boys. Forecasts change.
Rusty.

Information about the Kennebunk Beach Surf forecast
The above surf forecast table for Kennebunk Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kennebunk Beach can be found by selecting the local surf guide option on the grey menu. Our Kennebunk Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Kennebunk Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
